SPECIFICATION forming part of Letters Patent N0. 439,277, dated October 28, 1890.

Application filed July 9, 1890. Serial No.358,159 (No model.)

To a/ZZ wiz/0111, t may concern:

Be it known that I, WILLIAM H. IZARD, a citizen of the United States, residing at Belton, in the county of Bell and State of Texas, have invented a new and useful Band-Cutter and Feeder, of which the following isa specifcation.

` This invention relates to band-cutters and feeders adapted to be employed in connection with thrashing-machines and the obj ect thereof is to provide a machine of this character which will receive the sheaves, cut their bands, Spread the grain, and feed it forward in regulated quantities and at stated intervals, all in a manner and by mechanism effectingimprovements upon devices of this character heretofore constructed.

To this end the .invention consists of the specific construction and relative arrangement of parts, hereinafter more fully set forth, and illustrated in the drawings, in which-- Figure l' is a general perspective view of Fig. 2 is a central longitudinal, and Fig. 3 a central transverse, section of said machine, thelatter being takenv on line 3 3 of Fig. 2. Fig. 4 is a front end view. Fig. 5 is a plan of the entire machine with the hinged table-leaves removed. Fig. G is an elevation of the left side of this machine. Fig. 7 is a detail in perspective of the trough and its operating mechanism. Fig. 8 is a detail perspective of the mutilated gear.

The frame-work of this machine comprises longitudinal side beams F, connected by vertical end beams ll at the front and B at the rear, each of which pair of vertical beams' carry. cross-beams A -at the ends of the machine, as shown in the several views of the drawings.

Upon blocks C at the outer ends ofthe cross-beam A, which is at the rear end of the machine, are mounted short horizontal beams D, which are in the same horizontal plane with the cross-beam A at the front end of the machine, and these short beams D are connectedwith saidfrontcross-beamsAbyboards, forming tables S along the top of each side of the machine, as best seen in Fig. 1.

The cross-beam A at the rear end of the inachine is adapted to rest upon the front frame of the thrashing-machine, a part of which is shown in dotted lines, and projecting downwardly from the lower ends of the vertical beams B and from a block E, connecting them, are braces 30, that are extended and connected to the cross-sill of the thrashingmachine, so as to hold the band-cutter and feeder in proper relative position thereto, as will be understood. Metallic straps or other suitable connections V35 are preferably attached to the cross-beam A at the rear end of the machine, and are to be connected to the front frame of the thrashing-machine upon which this beam rests, the connection being effected by screws or bolts or any suitable manner.

At each end of each table S is a 'journalbox 23, in which is mounted a shaft 23', carrying at the front end of the machine a double-grooved pulley 24, and over these two groovedvpulleys passes a twisted belt 24.

Mounted upon each shaft 23 is a hinged table M, having two pairs of longitudinal slots R through its body, and over a roller on the shaft 23 and a similar roller m in the outer edge of the table passes an endless belt or apron N.

In the frame-work of the hinged tableleaves are pins n, which engage notches in the edge of a slot 36 in legs 36, which extend thence downwardly to the ground, as best seen in Fig. l. Y

The main operating-shaft is journaled in boxes 1, secured upon the upright beams mounted in boxes 4, carried by the vertical beams H at the front end of the machine.

Mounted in boxes 5, just above those numbered 4, is a shaft 80, which I shall call the knife-operating shaft, because it drives the knife, and on the right-hand end of this shaft is a crank 82, to which is connected a pitman 13, having a slot 83, loosely engaging a pin 84 in oneV of the side beams F of the frame-Work, as shown in Figs. 2 and 6. the pitman 13 is pivoted to a crank,85,wh ich is keyed to one end of Ya transverse finger- IOO The vother en'dof end of which vertical shaft has a crank 103.

In this manner power which is applied to the drive-pulley 2l communicates motion to the Various parts of the machine.

8 is a fork whose prongs extend through transverse slots s in the table S, and whose body basa slot G2, engaging a pin 63, carried in the outer end of a bracket 3, secured to the left-hand side beam F, and the lower end of thisVv fork hasanotch 64, which engages a crank 65, formed in the body of the longitudinal shaft 60. There is a similar fork at the opposite side ofthe machine whose lower end is pivoted to a slotted pitman 9, the body of which slides. loosely on a pin; 6, carried by' abracketbeneaththe machine, and the other end of which has a notch'66,-alsoen-l gaging said crank on the longitudinal shaft 60. By this meansthe two forks 8 are caused to operate alternately, each rising vthromrh the outer ends of the slots s and moving .in-Y wardlytherein, then descendingand return-l ing to lthe pointof starting, and the forks are guided in their movement andY directed into theslots s by lingers 38, as seen in Fig. 6.

In the opening..between thetwo tables S andateach side thereof is a longitudinally- Vslotted guide-track 11, andv in these .tracks travel the feet o of a block 19, whichsupf portsthe trough O. The latter travels longitudinally within 4this opening and is forced normally; totherear-that is, towarduthe thrashing-machinebya spring 110, asA shown in'Fig. 2. At the front end of this trough-is an-upright-end-piece U, having a Anotch 111, for apurpose to appearhereinaften'and con-Y nected to this end piece -is a right-angled bracket'112, provided-with a longitudinal slot 11.3 in its lower member, through which passes a setfscrewllm into the bottom of the Jtrough.

By this means the end piece can be adj usted as desired within the trough.` The other end.

ofthe latter has-wings P'atv its sides normally distended (when. the trough is -proj ected to the rear, as seen in 5) by straps 115,which connect the free ends of the Wingswiththe short horizontal .beamsD The bottom ofthe trough-'O is extended, asat O, vso asto be -of the same length as the wingsP when folded, Fig.-2,and in this-extension are seated fingers 11"?,fora purpose to appear laten on. The

block 119 carries two rollers 118, which are,-re spectively, engaged-by the lingers 26,"which are mounted -fupon the linger-shaft 90, hereinbefore described, and when saidishaft -is rotated'theV-ingers draw the block,-and With-it the trough, forwardly against the tension of said spring, the latter suddenly returning said parts when the fingers disengage the two rollers in a manner which will be understood.

1n some cases it may be desirable to provide a releasing-bar or trip-lever 119, pivoted in one of the tracks 1l and engaging a pin upon the trough, and the lower end of this lever is operated at proper moments by a cam 27, adjustably mounted upon the finger-shaft 90 by a set-screw 26.. The function of this tripping-lever is to hold the trough retracted until one of the forks 8 has fed a bundle into it, andY then to release the trough and allow its spring to throw it suddenly outward but it will be obvious that 'nearlyt-the-same result could be accomplished by setting thesfingers 2G upon the fingerfshaft by theirset'screw26.`

The letter I designates a central beaml at the front end of the frame-Work .and projecting above the tables- S, and to the upperendv shafts 17 Vat the upper end .ofthe;postflfand'A passes over:` another sprocket-wheel S1, keyed on the knifeLoperating;shaftabove mentioned.

arou-nd'the same and allows the grain Ato 'be' lscattered within. the trough before v:itis fedf therefrom to the thrashing-machine, .thisscatk tering being assisted by the lingers 117 in :the 1 extension O', as above stated. The shaft v70 has vaspline 71,*audonthis IIO shaft is mounted a mutilated gear 15, which" hasaa groove 7 2 engaging said spline, wherebyit must revolve withrbut can be v-inovedlolr A gitudinally upon the shaft; and anyfsuitable Y means may be providedffor somoving it longitudinally, as will-be understood, -orz it may be -held in position by a set-screwv'i, as seen f Thel face of this' mutilated gear-atoccupying one-fourth of the circumferenceofthe mutilated gear, and atthe otheraside the latter is providedwithbuta singlewbanklof r` teeth .'75, occupyingbutone-fourth of itslcircumference. The relative sizes of the-mutilatedgear 15 and gear S1 are such thataeaclrA bank of'lteeth on the'vfo'rmerwill impart oneV complete revolution to the lattelgand asfthebevel-gears 61 are of the same size the longif tud inal shaft 60 will make one complete revo lution Vduring the time that the mutilated gear 15 does; As said longitudinal shaft'during one'- revolution causes one 1 inwardV .movement-` of each of the forks 8, two sheaves -of grain Will'be Y which one of the smooth faces of the mutilated gear comes opposite the gear, and the trough stands in a distended position for a few moments. If but one side of the machine is to be used and the operator is feeding sheaves of grain upon only one of the tables, the mutilated gear is shifted, so that its single bank of teeth 75 engages the gear, whereby the trough is moved only once during a complete revolution of the shaft and one complete movement of the single fork that is being used, instead of twice, as was necessary when both tables were used, and hence both forks.

36 is a bar sliding loosely through a hole in the rear cross-beam A and having a slot in its body engaging a vertical pin 104: therein. The rear end of this bar is pivoted to the crank 103 upon the upper end of the vertical shaft 102, before mentioned, and the outer end of this bar is pivotally connected to a chute 32, which is swung by links 105 below a yoke 106, which may be carried by the thrashing-machine or by apart of the framework of this band-cutter and feeder, the chute being vibrated longitudinally by said crank 103, and thereby shaking and spreading the grain as itis delivered from the trough in a manner which will be readily understood. This chute may also. be provided with lingers 117, similar to thosein thev extension O and for the same purpose.

With this construction of parts the operators feed the sheaves onto the hinged tables M, and they are carried by the aprons N onto the tables S, whence they are moved by the forks 8 alternately from one table and the other into the trough O. The revolving knife severs the bands around the sheaves, and the wheat therein is loosened and spread within the trough. The latter is thrown forward at proper moments, and the grain thereby fed into the thrashing-machine over the vibrating chute 32 in a manner which will be `well understood, the opening of the wings P permitting the scattering of the grain into said chute. The guides T have feet which stick in the longitudinal slots R in the hinged tables M, and are manually adjustable, whereby the sheaves may be fed fat any desired point onto the feed-belts and by them into the trough, and the end piece of the latter is also movable therein, as above described, so that it may be set to the proper position to stand against the lower ends of the sheaves.
